SPECIFICATION forming part of Letters Patent No. 639,331, dated December 19, 1899. Application filed March 21, 1899. Serial No. 709,884. (No model.)

To all whom it may concern: for the purpose of increasing the body of the Be itknown that I, JAMEsI-LABERCROMBIE, delicate structure in order to enable it to a subject of the Queen of Great Britain, rewithstand the handling to which it is subsiding in Newark, in the county of Essex and jected in packing, transportation, and final 5 State of New Jersey, have invented a certain placing in .position in the burner, and, sec new and useful Improvement in Machines for 0nd, the trimming'or removal of any surplus Treating Incandescent Mantles, of which the length, so that the finished mantles will have following is a specification. the desired uniformity.

Many of the steps Fand G are swinging arms extending radimay be performed on a machine constructed ally from a hub H, loosely mounted on the in accordance with this invention, but I will shaft B below the spider-frame and carrying 5 5 describe the machine as adapted to perform devices for treating the mantles. I have the dipping and trimming steps, by shown the arm F as supporting a small vessel which are meant, first, the immersion in 001- or reservoir F, of collodion or other strengthlodion or other bath containing a strengthenening material in solution, and the arm Gas ing material in solution in a quickly-drying equipped with mechanism for trimming the I00 50 solvent applied to the mantle after the burnskirt of the mantle.

ing off and shaping have been effected The arms Fand G are shown at a right angle to each other, and both are for convenience joined to the same hub or sleeve H to swing together.

From the lower end of each slide extends a lateral arm or lug D which when the man tle is some distance above the vessel F will pass clear above a fin or web F on the pedestal F, but when the slide lowers slightly will engage the fin and compel the pedestal and vessel to travel with the slide by swinging the arm on the shaft B in the direction indicated by the arrow. The engagement takes place while the skirt of the mantle is still above the vessel and the axial line of the latter coincides with that of the former and the roller D has started down the incline E in the track. A further lowering of the slide dips the mantle into the solution, the bight or open loop m on the support allowing the complete submergence when the roller is at the lowest point e. The parts remain in the same relative position until the mantle is sufficiently impregnated, and the slide rises by ascending the incline E of the track, lifting the mantle from the vessel and releasing the lug from the fin, thus allowing the arm F and its connections to return to their original position through the influence of a spring or weight. I have shown a stop A projecting from the framework, in which is mounted a small pulley A and against which the wing F extending laterally from the pedestal F rests when the arm is not engaged. The parts are held in this position by a weight F on the end of a cord F running over the pulley and secured to the wing. The weight is preferably received in a trumpet-mouthed cylinder A", performing the functions of a dash-pot in softening or cushioning the shock of impact at the extreme of the return motion, and thus lessening the danger of spilling the contents of the vessel. It will be understood that any preferred form of govenor may be employed with orsubstituted for the cnshioningdevice just described. It is important that the return movement be made'with but little loss of time and also that the collodion be not wasted bythe overflow caused by its sudden arrest.

The dipped mantle continues its travel idly until sufficient time has elapsed to insure sufficient evaporation of the solvent, leaving the gum or other strengthening material, and is then ready for the trimming operation.

To hasten the evaporation, I provide means for bathing the mantle during the drying period in currents of air, preferably warmed, received through a pipe R from a blower or other source and escaping below the mantle through the open slot 1" in the curved pipe or segmental nozzle R.

The mechanism for trimming or cutting off the skirt of the mantle to the required length is carried on the standard'G' on the arm G. It consists of a short tube or ring G having a flaring mouth and plane lower face, and a revolving cutter-wheel G placed in such relation to the plane face as toshear off the lower margin of the skirt when the mantle is lowered within the ring. The cutter-wheel is carried on'the long arm of a lever I, mounted on the flange I of a sleeve 1 revolved by a belt J running on a pulley I from a larger pulley J 2 on a vertical counter-shaft J, driven by a small pulley J at the lower end, receiving a belt K from a large pulley B on the shaft B. The shaft J and sleeve 1 are supported vertically in bearings in the standard, and the lever I is so proportioned as to bring the cutting edge of the wheel into shearing contact with the lower edge of the ring when the lever is tilted by raising the short arm. This is effected by the movement of a vertical rod L, extending axially through the sleeve. Its pointed upper end is received in a conical recess on the under face of the short arm and its lower end provided with a roller L, resting upon a short segmental section of track N, supported by brackets reaching inward from the fixed work and having a short slightly-raised portion at at about its midlength. The cutter is held normally out of contact with the ring by the contractile spring 1 extending between the flange I and an arm on the lever, as shown, and the cutter stands just below the ring and concentric thereto,

leaving an annular space in which the skirt of the mantle may lower. The arms F and G are so set relatively to each other and to the positions of the slides D that at the time the lug D strikes the fin and moves the arm F, as described, a mantle, which has been dipped and dried, hangs vertically above the ring G and in axial line therewith, and by reason of the downward incline E in the groove or track E its slide sinks and lowers the skirt within the ring to a distance determined by the difference in level of this portion of the track. WVhile thus inclosed the roller L reaches the elevation n on the track N, forcing the rod L upward and throwing the revolving cutter G outward, and thus shearing off-that portion of the mantle below the ring. As soon as the elevation at has been passed the cutter returns to its central position, and the mantle is lifted clear of the ring by the upward incline E in time to allow the arm G to swing idly back to its first position when the arm F is released.

The finished man tles,with their supports M, are removed and untreated ones substituted at the donning and doffing station E between the limit of forward motion reached by the arm G and the backward movement of the arm F. The parts should be so proportioned and the speed so regulated as to allow sufficient time for the change. I have for the purposes of illustration shown only four slides D; but it will be understood that there may be as many more as the size of the spiderframe will accommodate, while allowing sufficient space between for the proper performance of the treatment at each step.

Modifications may also be made in the forms and proportions and in other details of means for returning each to its place, as will be understood.
